U can see that he bought a kit. I’m sure it has instructions. If it’s too quick for u, go to utube settings & slow down playback speed. Personally I prefer condensed short visual vids with no unnecessary backstory or time fillers. Usually when I go to these diy vids I’m in a hurry lol.
I used to work in an structural engineering firm and we'd use sika products when we needed to do a crack repair project. Works well although when it came to foundations, we had to be more thorough. Usually we'd have them excavate the back side as well to make sure the cracks weren't all the way through, check for water leakage, etc. Suggest repairs, etc. Saved a lot of older buildings in the downtown LA area doing this as well as around all of LA. Most of these buildings were constructed back in the early 1920s.
I've got a 1914 house in Chicago where the previous owner did a patch job 25ish years ago. I love these old homes/buildings. So worth saving. There's just no f'n way one is going to build new and have it be as high quality unless you have massive $$, even then . . .
I have previously; • thoroughly clean the cracks • resurface the inner face of the crack creating a semi smooth surface • cut a piece of garden hose, slice it vertical, tuck in the crack with vertical opening facing exterior • hydraulic cement or something over the hose and crack • drill into the floor through the pad accessing the drain tile. Allowing the water to flow in a controlled manner. Horizontal cracks are an entirely different story. I learned this years ago being that you CANNOT STOP WATER only try to direct the flow. wondering if anyone else is familiar with this technique. Good video. Thank you for your time and efforts.
It would be better to use injection packers and make sure the sealant penetrates to the outside of the foundation for larger cracks/failures. Then address the exterior and redirect the water away from the foundation if possible. The system he is showing here is the same principal, as the injection material will penetrate through the wall. Your idea will let the water seap under the floor and could cause other issues unless there is a french drain or some place for the water to go.
@@stringlarson1247correct. The injection seals the water out all the way to the exterior surface. Allowing the water to still seep through the crack and drain down a hose into the tile is allowing the concrete to be degraded over time. All of the concrete surrounding a crack needs to be chiseled back because that section, exposed to water often, is now weaker than the foundation wall. As far as I've read, when people try to waterproof a basement from the inside, they are allowing the concrete to hold moisture and not breath which causes not only deterioration but will also cause mold and mildew to form.
I have a very thin crack that's leaking every time it rains. It'll cost me upwards of $16,000CAD to get it repaired. You make this look very easy and worth looking into making it a DIY project.
Used a similar product on 2 cracks in my basement years ago and have had zero problems, only difference was had to mix my own cement, of course good gutter drainage and landscaping.is also key.
Nice quick video, thanks. I'd suggest getting a vacuum attachment for the grider. I have one on for the angle grinder and one (built in) for the Milwaukee M12 3" cut-off saw that I use for lathe and plaster walls. Works great. That fine dust can/will go everywhere for days.
Makes sense bc the previous owner of my home applied concrete repair over the crack and it doesn’t last long. I also had a home with a stone foundation that had water coming in. The first recommendation I received was to make sure the grading was sloping away from the house and also invested in 6 inch gutters. That really ended the water from entering the foundation.
Oh man this video saved my ass. I just noticed a vertical crack in my foundation and was shitting my pants thinking I’ll have to have the whole thing redone.
I had a decent size one but decided to hire a foundation professional contractor to fix it. They charged me $1200 to fix the crack and add a moisture barrier to it. The epoxy they injected is rated like 8000 psig, so it is much stronger than concrete. I haven’t had an issue since then.
This is exactly what I needed to do. Now I have 2 questions one what if there is a crack in the outside do you do the same thing after you dig a hole. 2nd question I have a leak coming from where the wall meats the floor and it doesn't leak too often but would I be able to just seal the inside or would I need to to the outside
Hello. I was in total awe until the end. Please show us how to properly remove the tabs before I purchase this rather expensive kit. I’m super excited to invest, but want to do it the right way & save $$$ on hiring a “pro”. Also, do we have to use all of the tubes, or is there a certain amount of coverage per tube? I read in some comments here that you’ll know when to move upwards onto the next tab once the product begins oozing out above. Thank you for what you have offered ❤.
Pretty good video, but you should have at least held up the box better and explain the products you're using and what that secondary thing you're squirting in with the hose is. (Please don't take this as hostile) Was that the same material, or a secondary material to take up any voids. I'm a contractor and I'm going to have to do this in about a week or two clients own. Looks like a decent product . Sika usually has top-notch products.
*WINNI* Bravo well done, thank-you sir for taking the time to show us how it's done. I've been looking for a solution for the 2 cracks I have in my foundation. GOD Bless.
Hey 👋 buddy I never saw that type of thing before were you put those plugs on the wall and push stuff in there I bet that is strong 💪..good video buddy 👍 👏 👌 😉
Thanks for the video - I plan on doing similar repairs to my Dad's old 1948, which has cracks in foundation due to improper plantings ( already removed the bushes). You will need to make a video about the caulking gun. 💕
Depending on the sealing product, it needs exposure to air to cure properly. Putting the sealant in behind a layer of concrete could prevent it from curing and adhering to the substrate.
Thank You! 🙏What kind of green gun do you have for squeezing epoxy at the beginning? 🙏For much smaller crack Matvey foundation company gave estimate 2800$ and described exactly the same process. Material is max 150$. And why chipping concrete with grinder to make bigger crack? To get more epoxy there? 🙏 Thanks. I have no one to help me and no choice but to try it. Need to keep elderly mother and dog is save home. Otherwise have to move…
Movement caused the crack. More movement will once again split the materials. Wouldn't some metal 'ties' cut perpendicular to the crack and bonded in, help keep everything held together?
I had a few cracks repaired on my foindaton wall and it has been 3 years and there has been no sign of any water entering through the repaired cracks. I had a contractor do the repairs.
My contractor did a similar process but instead used plastic tubing, so when he injects the wall, we know it is full as it runs out of the upper tube. He used pencils he cut to stop up the holes. When done everything stays in place including the now glued ports. The wall is just put over it. Usually there is some type of insulation which creates that much of a gap no matter what. I like this method but couldn't see how anyone would know the fluid has filled the entire void. Note he did some many years earlier with the exact same process and they are holding strong.
Hi, so far I have seen so many videos about fixing cracked walls and I like yours the best. May I ask where did you buy all the tools from? Hope to hear from you with many thanks.
Hi is there any place to actually buy the kit because it’s sold out everywhere and literally can’t find it after searching nonstop even on the sika website !!
Kevlar strap sealed on with epoxy inside and out if needed. Bullet proof and waterproof . Kevlar ‘s tinsel strength is like 100 x stronger than the concrete itself . One and done.
This is a temporary fix. I can't help to have noticed that you didn't wait when injecting the epoxy until it came out of the lower port and then close that port off before proceeding to the next above. I'd be concerned that I didn't have the crack completely full. Did I miss something?
I chisel the crack 1” deep v shape and fill it in hydraulic cement and cover with drylok. I did 10 foundation cracks and not 1 leaked. It’s been over years.
How do I get a professional to do that kind of fix, I keep getting companies that try to push the patch job that is a temporary fix and nobody knows how to do that
I have done many crack repairs but I use Water Plug (more near color of concrete). Embed small tunes as you go. Sets immediately. Use use LV or low viscosity epoxy. Sets overnight. Grind off. Practically invisible. Even bonded topping slab that curled off the original.
You can skip the two steps grinding the crack and spraying it out. At each port entry drill into your foundation 4 inches this will get the sealer in deeper to your foundation you may want to seal the outside crack as it will flex and seal the outside.Also this product works the best if you put just a small shot of water into your port before you inject it it actually will activate it.Used this products and others sealed many foundations never had a issue in 30 years.
I'd drill in a foot on each side of the crack to the outside..then do your injection of setting epoxy ..then anchor inside and outside together to get a absolute secure hold. Same procedure as a driveway crack with inset rebar across the crack. That epoxy ain't gonna hold much for long. Ya gotta secure that foundation with cross section rebar using your epoxy into the cross cut holes then push in the rebar.
My house is only 4th year now but it has a wide long crack wall. Also the floor is sinking I don't trust anyone who want to solve the problem. Any advice with this?
sounds like you have a settling foundation. sucks. builder's warranty? what does your insurance say? also, if you think there could be some erosion around your fondation over time from rain, you could improve rain water management.
please tell me where you get sikadu crack repair kit for concrete and masonry i see you do that job i love to lean how to but i dont where to get the kit .
Can this work on the floor foundation in a townhouse? Can someone please respond ASAP please. I’m remodeling a townhouse and found a crack across the room today. Thank you I’m advance 🙏🏾
First video I have watched that had really good prep work which is important if you want this to work. I have one question thou. How do you prevent the epoxy from oozing out of the crack on the outside?
I wish we could have seen the epoxy from the outside above the window. I imagine the rest underground would hydrolock with the soil, wouldn't be hard to overfill the cavity. Do the black plastic bits have 1 way valves in them?
The best way to fix this would be to excavate the outside foundation wall and repair the crack from the outside AND inside. BUT if you don't have access to the outside for whatever reason or just don't want to put in all that effort (and money), then I would use a large grinder and try to grind out about 2" width by 5" deep section of the foundation and use HYDRAULIC CEMENT to fill it. Hydraulic cement is waterproof. Sika products are more for walls and floors that do not have static water pressure pushing water into the wall like a sidewalk or above ground concrete wall.
Hopefully no one follows your advice regarding hydraulic cement. Hydraulic cement is harder than your wall. They will expand and contract at different rates, causing micro cracks and future leaks. Water behind the hydraulic cement will also soften the wall concrete and cause separation between the two. A proper 2 part polyurethane epoxy injection will fill the crack from top to bottom, inside to outside. The polyurethane will flex with the wall and you won't have water intruding into the wall softening it. No need to dig it up and fix it from the outside I made a living fixing cracks that people filled with hydraulic cement. I didn't catch the name of the products shown in the video. But it wasn't a high pressure injection, it didn't look like a 2 part cartridge and I didn't see it flow from one port to the next. So, I'd bet this ends up leaking sometime in the next 5 to 10 years.
Unless one checks the foundations that is only a good cosmetic repair. which will not hold if the foundation are moving due to soaking , One needs to hink much deeper. that that.
This repair is only temporary, as the crack may have resulted from differential settlement. It is necessary to excavate extensively beneath the foundation to inspect and prevent the occurrence of another crack below. In addition, a thorough foundation repair, including underpinning after careful excavation, will provide a more durable and lasting solution.
Why is your video INCOMPLETE? Did you explain what you were using? How it’s supposed to work? What it looks like when finished?
Google is free. You can clearly see what the product is in the video, and when he's finished injecting... That's what it looks like.
i will assume he is using 2 parts of epoxy, the grey layer to seal the surface then injection inside will mix/contact with grey part.
U can see that he bought a kit. I’m sure it has instructions. If it’s too quick for u, go to utube settings & slow down playback speed. Personally I prefer condensed short visual vids with no unnecessary backstory or time fillers. Usually when I go to these diy vids I’m in a hurry lol.
All these videos end there with those plugs in the wall . How does this story end ! 😭

I have previously;
• thoroughly clean the cracks
• resurface the inner face of the crack creating a semi smooth surface
• cut a piece of garden hose, slice it vertical, tuck in the crack with vertical opening facing exterior
• hydraulic cement or something over the hose and crack
• drill into the floor through the pad accessing the drain tile. Allowing the water to flow in a controlled manner.

Hey, thanks for the vid, wondering if there is any sort of indication when each injection point is full?
You start at the bottom and when the nipple/tube above has some poly in it you know it is full and move up one.
As shown here you start at the bottom, however what isn’t shown here is when the next tap above starts dripping you move up to that one and so on.
How much are they paying you ? That stuff is garbage.

First video I have watched that had really good prep work which is important if you want this to work. I have one question thou. How do you prevent the epoxy from oozing out of the crack on the outside?
I think the soil on the outside will be compacted enough to stop it from going anywhere and I think some foundations have a plastic wrap on it.
I wish we could have seen the epoxy from the outside above the window.
I imagine the rest underground would hydrolock with the soil, wouldn't be hard to overfill the cavity.
Do the black plastic bits have 1 way valves in them?
Free is price for that tractor. But your most watched video was that dozer what dumpster Dave purchased from Andrew Camarata
Why not spray the whole wall with closed cell spray foam?
It is a temporary repair unless settlement issue has been resolved.
The best way to fix this would be to excavate the outside foundation wall and repair the crack from the outside AND inside. BUT if you don't have access to the outside for whatever reason or just don't want to put in all that effort (and money), then I would use a large grinder and try to grind out about 2" width by 5" deep section of the foundation and use HYDRAULIC CEMENT to fill it. Hydraulic cement is waterproof. Sika products are more for walls and floors that do not have static water pressure pushing water into the wall like a sidewalk or above ground concrete wall.

Where can you purchase this kit? Home Depot, Lowe's?
Did you ever find it? I tried home depot today. And they did not have it. I have not tried lowes yet
I think it would be better to start injection from top first so that paste can flow down inside under force of gravity.
Filling it from the bottom evenly forces the air out.
